It is also apparent that upon discharge of the coin, the cradle will then return from the position shown Fig. 4 to that shown in Fig. 1, which is the proper position for the deposit of a subsequent coin.

When a coin having a diameter less than that of an acceptable coin, but having the proper Weight, is deposited, it is apparent that the coin will displace the cradle to a position shown at the frame l wherebyvprojection 4 oi' the abutting member' 3 will dislodge tnesuspended coin from projection lu and pin le and cause it to iall by gravity into tne rejection passageway i9.

. Having described my invention, I claim;

' ,1. A coin separator comprising i'rame means forming anenti-ance and an acceptance passageway and a junction open to each said passageway, each said passageway adapted to conduct gravity propelled coins edgewise therethrough in a substantially vertical plane, a cradle pivotally secured to said frame means adjacent to said junction and adapted -ior rotation in two directions from a normal position, abutment means integral with said frame means for arresting the rotation of said cradle -when said-cradle is rotated a predeteiininedfangle in one direction from its normal position and for arresting said cradle when moved a second predetermined angle in oppositedirection from said normal position, said cradle having two integral spaced projections extending into saidjunction in the path of coins descending in said entrance pasfsageway, said projections spaced to intercept and temporarily retainthereon a" coin of acceptable weight and diameter, :urging vmeans for normally urging said cradle into said normal position with .one of said projections uppermost, guide means on said frame means-in saidentrance passageway for directing a said coin descending therein in a direction toward and against the uppermost 'of said projections for rotating said cradle against the v restraining action of said 'urging means through the irst said angle in one direction and whereby .said coin under the influence oi gravity willviurther` descend and straddle said projections and rotate said `cradle in opposite direction through Aan angle equal to the sum of both said rst and second .angles to transfer said coin Afrom said cradle to said acceptance passageway .at a predetermined. velocity.

' of acceptable weight and diameter descending in said entrance passageway to said acceptance passageway, a pair of spaced projections integral with said cradle extending into said junction for intercepting said coin, a rst and a second abutment integral with said frame means positioned in said entrance passageway in predetermined spaced relation with respect to the axis of rotation of said cradle for guiding said coin against a predetermined one of said projections, urging means for urging said cradle in a normal position, stop means integral with said frame means for arresting rotation of said cradle when moved in one direction fromA said normal position, a second stop means integral with said frame means for arresting the rotation of said cradle when rotated in opposite direction from said normal position whereby a coin descending in said entrance passageway will first impinge upon said rst abutment and be guided against one of said projections and rotate said cradle against the restraining action of said urging means in said one direction and whereby said coin will further descendand impinge upon said second abutment and be guided to momentarily straddle both said' cradle projections whereupon the action of gravity on said coin will rotate said cradle in lsaid opposite direction to transfer said coin from said entrance passageway to said acceptance passageway at a predetermined velocity.

3. A coin separator for separating coins of acceptable weight and diameter from underweight coins comprising in combination frame means forming an entrance a rejection and an acceptance passageway, each said passageway terminating at a junction, cradle means pendantly suspended to said frame means and retained by gravity in a normal position, a iirst and a second projection integral with said cradle means and extending into said junction for intercepting and temporarily retaining a coin of proper weight and diameter thereon, said rst projection normally positioned uppermost in said junction, stop means integral with said frame means positioned for arresting the rotation of said cradle means when it is moved a predetermined angle in either direction from itssaid normal position whereby a said coin descending in said entrance passageway will be guided thereby to impinge upon said 'rst projection and rotatesaid cradle in one direction and will further descend to straddle both said projections whereupon the action of gravity on said coin will rotate said cradle in opposite direction to transfer said coin from said entrance passageway to said acceptance passageway andr REFERENCES CITED y The following references are of record in the file of this patent:v i l 'l' innTiiiDA STATES PATENTS Number Name Date 2,376,357
